Applications and ordering

• Typical applications: compact linear positioning, instrumentation, pick-and-place, small robots and OEM devices (verify compatibility with system requirements)
• Ordering: specify motor type (External / Non-Captive / Captive), required lead screw lead, stroke and rated voltage/current.
